new entry: logrep

[Carlos Bueno]

Howdy, I'm working on a new entry for WF2. It's in Python, and it's
actually a production utility called logrep/wtop. It definitely won't
win any line-count contests, but I wanted to end up with something
people can use every day.

I've started simple: if --x-cores is greater than one, it forks N
child processes and feeds them individual lines round-robin. Each
child compiles their own statistics and they are reconciled at the
end.

This seems to hit the wall at 10 threads or 28,000 lines/sec. But for
a first try I think it's pretty good.
